I was threatened often with the expression " wash your mouth out with soap," but, thankfully I don't recall having it done to me. Nowadays maybe it is considered child abuse like a spanking. The spankings, I do remember. And being threatened with my father's favorite weapon - his army belt.
Belt from dad, wooden spoon from mom. I had a bum made of adamantium, there were many spoons broken over these glutes!
(Yeah I was a pain in the patella of a child...)
